IlIIAGI-IINE MAKING STEIYIS FOB INGAINDESCENT LAMPS.

Application filed July 1, 1926. Serial No. 119,883.

My invention relates to the n'ianuitacture 01" incandescent lamps andparticularly to an apparatus iorautomatically forming, inserting andarranging hooks or supports on incandes'cent lamp stems upon which thefilaments are draped.

i The object ot the invention generally is a machine whereby the formingof the hooks or supports and the insertion and spacing there of in andabout the stem urbors may be automatically and rapidly etl'ected with aminimum of labor and attention. A particular .object of the invention isa machine of this general character but readily adaptable at the will ofthe operator to the insert on of a variable number of books and supportsproperly spaced, depending upon the adjustn'ients desired, theadjustment and shifting lfrr one type of stem to another being readilyetfected and the proper number of hooks in- 1 withoutvaryin the speed ofoperation sort .a of the hook inserting device.

Referring to Figs. 1 to l inclusive, I have indicated a mount or mountstem or electric incandescent lamps or the like into which are tobeincorporated the hooks or supports for the filaments to be drapedthereupon,

and my machine is adapted to this purpose. The standard stem for anincandescent lamp is indicated in Fig. 1 and includes a glass rod 1. in2 the rod 1 has a button 2 formed on the upper end thereof and thesupports or hooks 3 are inserted radially into this button. In Fi 3 abutton 4: is formed near the lower end of the rod and hooks 5 areinserted radially therein. Fig. 1 shows the filament 6 draped about thesupports and 5.

My novel machine for forming the buttons and inserting the supports orhooks will now be described. Referring to the drawings, particularlyFigs. 5-9, my machine includes a main supporting frame or base 10 andupon this base there is revolubly supported a main frame or spiderconsisting of a multiple number of radially disposed supporting arms 11.And the particular example illustrated is a six-position machineincluding six of these arms 11. Each oi these arms 11 has journaled onthe outer end there of a stem holder 12 having projecting up therefromsuitable supporting and alining arms 13, 14: and 15 which are adapted toreceive and support the stems indicated in Fig.

1. Each arm 11 together with its stem support 12 is adapted to beindexed around from position to position and to occupy each ot thepositions A, B, C, D, E, F of the machine. Positions A and B are theunloading and loading positions, and upon advancing to the position Gthe button forming mechanism ndicated generally by G goes into operationto form the buttons 2. At position D the hooks or supports 3 areinserted in the buttons 2 by means of a suitable hook or supportinserting mechanism designated generally by H. At positions E and F theother buttons 4- are formed and the hooks inserted respectively by thebutton forming mechanisms G and H. In Fi i the filament mount isindicated as having five of the hooks or supports 3 and four of thehooks or supports 5 and I have devised a machine iniii eluding readilyoperable and adjustable means for varying the number of supports orhooks to be inserted with the proper spacing thereof according to eachadjustment, and ordinarily in con'ui'iercial lamps it is desirable tohave one less hook at the lower end of the mount; than at the upper end.Ac cordingly my machineis' adapted to these purposes.

The spider, including the arms 11, is mounted upon a hollow shaft whichis suitably journaled in the main frai'ue it), and to this hollow shaft20 there is secured a geneva 21 which is engaged by a Geneva driver :2to advance or index the spider one position at each revolution of thedriver 22 the latter being carried by the shaft 23. The main drive shaftfor the machine is indicated at 31 (l-ligs. 5, T) which may becontinuously driven by any suitable power means, as for example, anelectric motor (not illustrated). The drive for the geneva includes the'gear 2% on the shaft 2-3, the gear journaled on the hollow shaft 20, thegears 26 and ($6 on the shaft 17, the pinions 27 and 28 on the shaft 18,and the pinion 29 and the bevel 30 on the main drive shaft- 31. Betweenthe gears 27 and 28 there is disposed aclutch P controlled in a mannerhereinafter described.

The button forming mechanism G includes a reciprocable rod or shaft 32which is mounted within the hollow shaft 20 and carrics on its upper enda radially disposed arm 33, this arm as carrying on its outer end anadjustable arm S t. The latter is screwthreadedly adjustable in a.sii'i'iilarly threaded opening in the outer end of the arm 33 and has atightening nut and screw 35 for fixing the pressing rod 34: in adefinite llXOfl position. The rod has on its lower end a. pressingbutton or knob 3 s and the arrangement is such tlat as each arm 11 ofthe spider moves over to position C the stem of rod 1 is carriedimmediately below and in line with the pressing rod 31-. At this pointthere are disposed the heating torches no for directing the heatingflames against the upper end of the glass rod 1 in order to soften thesame. While the hooks and supports are being inserted at position D inthe next succeeding step the torches soften the end of the stem rod 1and the rod 32 with the button forming arms 83 and 3% is reciprocateddowmvardly to bring the knob 34 into engagement with the softened end ofthe stem to form the button 2 thereon. Normally the button formingdevice is maintained in its inoperative position by a spring 37, and themechanism for actuating it against the tension of the spring includes acam 38 carri'et'l by the gear 24; which actuatcs a forked lever 39; thelatter being pivoted for pivotal movement about the axis'att) andhaving; fingers ell passing through suitable inmost slots in the hollowshaft 20 and engaging the rod 52. There is an intermediate pin it!between the cam 38 and a bridge 43 fastened to the under side of theforked arm 32), this pin 42 passing through a suitable opening in thebracket which carries the tleneva driver shaft The button formingmechanism G, therefore, is operated simultaneously with the operation ofthe Geneva driver 2:5. The button forming mechanism U is identical withthe mechanism ti and is operated simultaneously therewith to form thelower buttons l on the stem as each arm ll of the spider advances to iheposition i of the machine the torch 21h indicated as having a doubleliamc playing upon the porlieu of the rod l in which the button is to beformed.

At the position i) of the machine the hooks or supports 3 are insertedto the required number in the button formed at the end of the rod by themechanism ll, this mechanism as hereinafter described, including anautomatic wire support, feeding, inserting and cutting-oil mechanism.its each stem comes to rest at this position the mechanism H is startedin operation, and after insertion of each support; or hook radially inthe button, the stem support; 13 with the stem carried thereby isrotated through a definite predetermined angle depending upon thespacing to be given the supports. The drive for the hook insertingmechanism includes a beveled gear :30 on the end of the main drive shat't lh a cm'respoIuling beveled gear bl which is capable of beingcoupled to the shaft by means of the clutch N, a pinion 53 carried bythe shaft 52, a. large gear 5-1; and a small gear 'lhc clutch ix" alsocontrols the nu-chanism tor indexing the stem around after the inscrtionof each hook and this mechanism is as follows: The gear 54; meshes withthe small r gear 55 which is carried by a small, shaft 57 and thisshaft- 57 in turn carries an actuating cam (Fig 7 5). The cam 51H uponeach revolution of the shaft 57 actuates one end of the pivoted lever.39. the latter at its other end engagingthe end of a reciprocal'ilerack tit), suitable rollers (ll being provided between this lever andthe reciprocable rack for minimizing wear and friction. The rackactuates a sector or segment (52 which is journaled upon the sha t't(it-l and has a one-way clutch connection with the gear (Bl which inturn is journalcd upon the shaft 63 and is connected through theintermediate gearing 65 and (it; with the gear 67 (Fig S, 10) whichdrives the clutch 68 for the stem holder 12. The one-way clutchmechanism between the sector (32 and the gear 6- includes v plurality ofdriving cams 69 which are pivotally carried at their inner ends by adisc member To listed to the, sector (32, the pivotal points beingindicated lho at 71. The pivoted cam members 69 are carried within arecess termed in the gear IllOlIlbCl' 64, and in one direction ofmovement of the sector (32 ifrictionally engages the periphery of thedrum surlace thereof to etfeet a driving connection, suitable springs inbeing provided to urge said connecting members 69 in a direction to forma driving connection. At each reciprocation, therefore, of therackthrough the ratchet and gearing shown the stem holder 12 is rotatedthrough a deiiniteangle and in this position comes to rest for theinsertion of another hook or support. The angular movement may beadjusted and varied to effect the hook or support spacing desired byvarying the eltective stroke of the rack (30. In the particularembodiment shown, this is accomplished by providing an adjustable stop74:

for engaging the stop 75 carried. by the rack ('30. A sprlng '16 servesto return the rack (50 to its initial position, and by adjusting thestop 74llongitudinally oi the rack the stroke may be varied andaccordingly the angle of rotation imparted to the stem holder 12. In theparticular embodiment shown, the adjustable stop T l is carried by anadjustable shaft 77 mounted within a housing 78. A thumb screw 79 isprovided tor-moving the arm 74L back and forth to etft'ect the requiredadjustment, and a tightening nut 80 is shown for fixing the stop 74 andits shaitt in the adjusted position; It is desirable also to provide ascale 81 with a pointer 82 carried by the adjustable stop 74; forindicating theproper spacing for the number of hoclrsto be inserted inthe upper end oi? the stem rod. That is, by adjusting the pointer 82 tocorrespond to the numeral on the scale indicated, the hooks insertedaccording to the number indicated on the scale should have the requiredspacing.

The clutch 68 6, 10) is in the form of a disc with teeth on its uppersurf ce for engaging the lingers 83 on the bottom of the stem holds s12. lllhis clutch 68 is mounted upon a vertical reciprocable sleeve 84and is normally maintained in clutching relation with the fingers 83 bymeans o'lia spring 85, the sleeve 8% passing over the shaft 86 to whichis keyed the gear 67. The spring 85 surrounds the shaft 86 and isdisposed between the gear 67 and the lower end of sleeve 841:, thelatter being provided with a depending skirt 87 which forms a housing1501 the spring and carries a double collar 88. The sleeve 8% isslidable up and down the shatt 8tibut relative rotation is prevented bya pin 89 fixed to the sleeve and passing through a slot in the shaft 86.It is necessary to disengagethe clutch 68 when the spider with arms 11moves forward one position, and this is effected during the operation ofthe Geneva driver 22, he latter carrying a cam 99 on its upper sidewhich. is

so arranged that during the movement ot the spider it engages the treeend of a T- stemholders. and during this n'iovement ot the spider I haveprovided a pair ol guide pins )3 :torengaging a curved guide 94 (liig.9) in the stationary part oi? the machine and thereby maintaining thestem holder in its last angular position to which it was notched by thereciproraitiug mechanism.

1 have thus indicated the construction and functioning of thenimohanisn'i "for indexii'lg each stem holder 12 as it comes toposition 1) and also for ellt'ecting disengagement of the indexing drivewhen the spider moves froi'n one position to the next. At position F onthe n'iaehine where there is a hook inserting mechanism ll similar tothe mechanism H at position D, the stemholders 12 must also there beindexed around to properly space the hook supports inser ed in the lowerbutton which is formed at position E oi the machine. For this purposethere is a clutch mechanism 68 similar in construction to the clutchmechanism 68 just described at position D, the lever 91 which iscontrolled by the Geneva driver having a cross arm 96 corresponding tothe cross arm which functions with the clutch mechanism 68 inidentically the same manner in which it functions with the mechanism 68just described. The indexing is eitected through the adjustable strokemechanism above described including the sector 62, the one way clutch,the gear 64-, the gears 65, (36 and 67.

l The control mechanism whereby the in dexing oi, the machine, theindexing oi the stem holders and the operation of the hook insertingmechanism are automatically and properly timed with relation to eachother and whereby the machine may be readily changed from a machine formaking); stems for one number of books to a machine for making stemsincluding another ninnber ot hooks will. now be described. This control.mechanism includes a pair of control memhers I and II which aremechanically coupled together and driven in time relation with themachine and automatically determine the periods of operation and thenumber o'Ehooks inserted by the hook insertin mechanism H, H. Thiseffected throng-2h the control of the clutch ht which in turn controls,as aboi 'e indicated, both the ope tion of the hook inserting mechanismH and the indexing mechanism for the stem holders for properly placingthe hooks or supports inserted. The two control members I and II, whilemechanically coupled together during the operation of the machine, areadjustable with relation to each other so as to vary the period ofoperation of the hook inserting mechanism to vary the number t hooksinserted. In the particular embodiment illustrated these control membersI and II are in the form of disc cams carried by sleeves 100 and 101.respectively, which sleeves surround and are journaled around the shaft63. The ram I and its sleeve 100 are connected with the drive gear 102,the latter meshing with a bevel gear 103 mounted on the main driveshaft. These sleeves 100 and 101 carrying the control members I and IIare adjustahly coupled together for varying their relative positions bymeans of the set screws st carried by an arm 105 mounted on the sleeve101 and the cooperating circular toothed disc 106 carried by the sleeve100. By withdrawing the set screw 1.0 1 the relative position betweenthe sleeves and 101 and the control members I and II may be varied asdesired, and then the sleeves may be mechanically locked together byscrewing home the set screw 10 1 into registry with the opening betweentwo ot the teeth on the disc 106. The control members of cams I and IIetlect respectively the closing and opening of the clutch N with theconsequent starting and stopping of the hook-inserting mechanism and theindexing of the stem holders. For this purpose I have shown a lever arm107 (Figs. 12-13) for effecting the opening and closing 01 the clutch Nwhich lever arm is pivoted on the axis 108 and is rigidly connected withan arm 10), the latter being normally in engagement with the controlmember of cam II. The arm 109 upon being engaged by the raised part 110(It the control member II is urged outwardly in a direction to open theclutch N and into locking engagement with a bell crank lever 111, thelatter being biased into locking position by a spring 112 and having theend 113 of one of its arms adapted to engage a corresponding locking endof the arm 109. The other arm 114 of the bell crank lever bears againstthe cam or control member I and upon being engaged by the raised part115 of the cam or control member I the bell crank lever is actuatedagainst the tension of the spring 112 to a position to disengage andunlock the arm 109 and the lever arm 107 and upon the release of thelever arms 107 and 109 the clutch N is automatically closed. The clutchN includes a small plunger 110 and an actuating compression spring 117disposed within a recess formed in an enlarged part of the shaft 52 andan annular plate 118 fastened to the underside of the gear 51, thisannular plate 118 having locking recesses 119 For the reception oi theplung r 116 when in clutching engagement. The spring 117 tends to closethe clutch so that when the actuating lever 107 is released the clutchis automatically closed. llpon (he raised part 115 of the cam I throwingin the clutch for starting the hook inserting mechanisnn U. the indexingilltl"ll:l1llt-'l.l tor the stem holder at position I) begins to workand continues until the enlarged part 110 ol the cam II engages the arm10$) to open the clutch N, the number of books inserted and the numberot indexing operations of tho stem holder depending upon this period o1operation, the machine being driven at :1 constant speed. By 'aryingrthe relative position oi the raised parts 110 and 111' ol the cams orcontrol members II and 1. this period oi? operation may be lengthened orshortened depending upon whether the number of books or supports is tobe increased or decrcased,this varying adjust ment being ellected asabove indicated. Ordinarily the spacing oil the books or supports aboutthe stem is to vary inversely with the number of hooks inserted and thisadjustment is etlecled tln-ougagh the adjustment of the indexiinr strokeot the lllt'l'llilnism above indicated. i i'lter the completion of thehook inserting operation the spider with its arms 11 must be indeferl oradvanced to the nextposition and this is effected through a clutch lwhich is thrown into operation by a control member ll l This is carriedby the sleeve 101 (l izr. i to rotate with the control member ll. Theclutch l is of similar construction to lilo clutch N, namely embodying ar-lntch n: chanism similar to the plunger 110 and rollpling plate 118with a sprin; similar to tho Spring 117 normally 11!;(1I1t1 the clutchinlo closed position. The control member lll in the particularemlnnlinient illustrated is in the form of a cam disc being circularl'or the greater portion (it its vii-cumlcrenre. having a portion cutaway at 121. A. hell crank lever having one arm 122 in engagement withthis cam disc Ill normally holds the clutch P in open positimi throughits other arm 123 engaging with the clutch plunger, but when the controlmember ill rotates into a position where the arm 122 runs upon the cutaway portion 121 ol the cam disc, the clutch i is aulomrnicallv closedand continues to he closed until the cam III turns in a position suchthat the arm 122 rides upon the increasml diamet r thereof. During thistime when the clutch P is closed, the Geneva driver makes one revolutionand in doing so advances the Geneva 21 with the spider the distance ol'one position Qjf the machine and as above described during the movementof the Geneva driver 21 and the spider the cam comes into operation towithdraw the clutches 68 and 68 from the spindle holders. 1 p

The number of hooks or supports inserted may be varied within limitsdetermined by the time it requires for the control member II to make anapproximately complete rcvo lution. For example, it the :iidiustment issuch that the enlarged part Oil the cam I operates the lever 114E soonalter the enlarged part 110 of the cam II rides oil the correspondingenlarged part 109'of the arm 109, the cam II making nearly a wholerevolution before throwing out the clutch, this would correspond to themaximum number of hooks or supports insertable by a machine with theparticular drive shown,-as for cX- ample, twelve hooks or supports andfor a lesser number of hooks, the control member or cam II rotatesthrough an angleless than 360", after the cam I starts the hookinserting mechanism II and before the latter is stopped, depending uponthe number 01: hooks. For example, if there are six books to beinserted, the approximate rotation of the control or cam member II wouldbe 180 between the starting and stopping of the mechanisms, it the totalrotation of 360 corresponds to an. insertion of twelve hooks. In orderto minimize the loss of time incident to adjustments for less than themaximum number of hooks caused for example by the time required for thecomparatively slow moving members I and II to return to the initial.starting position after the insertion of the required number o't' hooksI have provided a special arrangement for eli ect ing a quick return ofthe members I andlI back to the initial position after the clutch N isthrown. out by the cam II. This tast speed mechanism includes a driveconsisting of the gear on the main drive shaft, a

bowl gear 127 meshingtherewith, a larger gear .128 on the snatt and thegear on the upper end ot the shaft es, the gear 125) being journaled fortree inovcn'icnt on the outer sleeve 101. so as to rotate continuously.This gear 129 has a clutch member on its underside including theplurality of pins 130 mounted within recesses oil the carrier 131. andin these recesses are disposed the spring pressed balls 132, normallyurging the pins 130 to project beyond the carrier 131. The sleeve 101also carries a clutch member 134 in the form of a slidable collar keyedthereto and an operating forked lever 135 pivoted at 136 on the mainframe and straddling this collar clutch 13.4. The free end of the forkedlever 135 carries a roller 13'? which bears upon and follows the upperside surface of the cam member III. The raised part 138 of this camengages the roller 13? and thereby actuates the clutchlll: into drivingrelation with the gear 129 and its corresponding clutch. This drives thesleeves 100 and 101 together with the control members at a substantiallyhigher speed than through the slow drive from the gear 102. A ratchetcoupling 140 is disposed between the disc cam I and the gear 102 topermit the fast forward movement of the control members. The fastspeedis continuous until the control members are brought tothe initialstarting position, whereupon the clutch 131 is thrown out of engagementto permit the slow s )eed drive to a ain become elleclive, the lever 135being retained in its upper position to keep the clutch 134 closed by adownwardly suspended U-shaped arm 1 11 which straddles the arm of thelever 135 and rides underneath the portion 135 thereon to hold it in thelifted position. The spring pressed plunger 14:2 normally urges the piv'oted member 141 into this retaining position. For throwing-out the fastspeed clutch just before the control cam I throws in the clutch N, thereis provided a control member IV mounted on the sleeve 100 with themeinher I and provided withthe raised portion 14l3,this raised part 1 13of the cam engaging the inwardly turned end of the holding member 1411to move it out into a position to permit the pivoted lever 135 to tallout of engagement with the gear 102, this occurring just. before the camI throwsin the clutch ll.

After the lower buttons are formed at po sition 13, as described above,each stem is carried to position F where the hook or sup portinsertingmechanism I-I inserts the supports in the lower button. The drive forthis mechanism includes the bevel gear 50 on the drive shaft, the bevelgear 51, the shaft 52, the clutch N t-herebetween, the pinion 53 carriedby the shaft, the large gear 5s: and the gear and the shaft 151. Aclutch M is disposed between the gear 150 and the shaft 151 so that inthe event asniallcr number of llOOliSOl supports is desired to beinserted in. the lower button, this may be eiiected by discoi'itinuingthe hook inserting mechanism II prior to the stopping of the hookinserting mechanism H. Ordinarily in commercial lamps the lower buttoncontains one less hook or support than the upper button and accordinglyI have devised a special automatic means for stopping the hook insertingmechanism H a sullicient time before the stopping of the mechanism H toavoid the inserting of the last hook or support. I accomplish this bymeans of a control or disc cam member V which is carried by the sleeve101 to rotate with the other control members. This cam member has araised part 152 which engages a lever 153 pivoted on the axis 108 andhaving an arm 15 1- rigid therewith for controlling the clutch M. Thisclutch M is similar to the construction of the clutch N above de- Hillscribed, namely normally tending to close the clutch and when the arm153 rides upon the raised part 152 of the disc cam V the arm 5 1automatically throws the clutch M out of gear and maintains it out ofgear until the clutch N is thrown out.

'The hook or support inserting mecha nisms H and H are identical and adescription of one will sufiice. Each includes a. vertical shaft 151(Figs. 1416) suitably journaled in a stationary part of the machine andcarrying on its upper end a-quadruple cam member S. The under side ofthis cam, as the shaft rotates, engages a plunger rod 161 which isslidably disposed in the main frame 162 of the mechanism,

and this plunger 1.61 engages at its lower end one arm 163 of a bellcrank lever, the other arm 16 1 engaging a reciprocating block 165, thelatter carrying a fixed gripper or jaw 166 and a cooperating pivoted jawmember 167. The latter is pivoted at 168, a spring 169 normally tendingto urge the pivoted gripper 167 into gripping relation with thestationary gripper 166. The grippers 166 and 167 engage the wire 170 andfeed it forward and insert it in the but ton of the stem when the.reciprocating slide is urged forward. The return movement of the slide165 is effected through a spring 171 disposed in a suitable recess inthe frame 162 and engaging a slidable plunger 172, the latter engaging apart of the slide 165 and normally urging it into retracted position.Adjustable screws 173 and 17 4 are provided for the bell crank lever16,3t to make the necessary adjustments. When the stem holder is carriedto either position D or F the support inserting mechanism is started andthe reciprocating slide 165 is urged forward to insert the end of thewire 170. In the meantime a torch 17 5 has its flame directed againsttheedge of the button and at the point where the wire is to be inserted toraise the temperature at this spot above the. temperature which it retains after being heated at the button torming position. Immediatelyupon the ad vancement of the grippers to insert the wire into the buttonat the heated spot an air nozzle 176 is caused to direct an air blastagainst the spot where the wire is inserted to rapidly cool it. Themechanism for etfecting this includes a. source of air pressure, (notillustrated), controlled by a valve 17 8 leading to the air nozzle 176.The valve 178 has a valve operating member 179 which is normally in aclosed position, but upon the rotation 01. the cam member S the camsurface or part 180 carried on the edge or side thereof comes intoengagement with the arm 179 to open the valve for a short time to causethe air blasts 176 to play upon the heated button. This cooling blastremains for a sufiicient time to cool the button, the

cam 186 being constructed and arranged to etl'ect this purpose.Ordinarily the bhist of air is turned on before the grippers .166 and167 begin their rearward movement, the grip on the wire 170 beingsullicientlv tight to feed the wire forward; but not light enough towithdraw the wire from the button. especially after it has been cooledby tlm blast. A spring 179 tends to keep the valve closed. After thegrippers 166 and 167 are withdrawn, a pair o1 pivoted cutting and1orming members 181 and 182 including the cutting saws 183 and the hookil'orming mcm hers 18e1-5 and 268 are brought into operation to severthe wire and form the hook 166 in the support. The two members 181 and162 are pivoted on the axes 199--1 and are lined to shafts 199 and 191,and by rotating these shafts against the tension o1 spring .166 theknives and ilormcrs are brought into ("(1- operation. The axle 191 has acrank arm 192 and the shal't oi has an operating member 193 at rightangles thereto. The cam 189 carried by tha cam member S on the upperside thereof operates a pair o1 similar slidable pins 195 which at theirupper free ends engage respectively the members 192 and 193 to operatethe cutters against the tension 01? the spring 196. This. as indicated,takes place after the withdrawal. ot the grippers 166 and 167. The hookforming members 1S-1-5 arc lixcd to the operating arms 161-Q ad'jm'cntthe knives, but the membe 908 is in the form 01? a small pinindependently movable and carried ly the oscillatable shaft 299.
